SERIES PS-ES
Electrospindles of square section for particular works on
CNC machine tools and birotatives heads.

•  This series of electrospindles is particularly indicated for all
    those applications where is required the assembling of the
    spindle on a surface or inside a bracket, for example in the
    5 axis machine tools or on the tilting heads.
•  These types of Electrospindles are made of alloy with high
    mechanical resistance in order to reduce the weight, they
    are supplied with powers up to 50 Kw and are equipped of
    tool holders ISO-BT or HSK.
•  The bearings’ lubrication is done by permanent grease
    without any kind of maintenance or with minimal air-oil
    system for high speed.
•  The Electrospindle and the piston are made in cartridge in
    order to never remove the square body from the machine
    tool, keeping unchanged the geometry and the precision
    of the machine tool ‘s head.
•  To increase the compactness of the Electrospindle all the
    services are made in the central part of the square body
    and are projected upon specific customer’s request.
